I am not a lawyer and although the globe, the font and the (image I used from the logo creator) are "public domain" the combination of these for your company in the manner I designed them would be considered propietary to your company...for copyright purposes (see the definition from dictionary below.......The ability to trade mark involves your name etc..and your logo......
I've added the copyright for "display purposes" only but I have not had a problem in the past...Thanx for your consideration.
We can proceed thru PM's if we are on the same page......

He should get a legal opinion..
In my 30+ years I have stayed as "clear" as possible regarding the legal issues, I'm confident on the copyright, although your thoughts are appreciated, maybe I've just been lucky, but the trademark is a different "animal".

The use of the symbols TM or SM are not governed by federal law. However, sometimes these symbols are governed by local, state, or foreign laws. Otherwise, you can freely use the symbols TM for trademark or SM for service mark to indicate that you are claiming rights to the marks without (or before) having federal registration.
Federal Registration Symbol ®
The traditional trademark symbol or federal registration symbol may be used once the mark is actually registered with the USPTO. Even though an application is pending, the registration symbol may not be used before the mark has actually become registered. The federal registration symbol should only be used on goods or services that are the subject of the federal trademark registration.
[Note: Several foreign countries use the letter R enclosed within a circle to indicate that a mark is registered in that country. ​
